The present provements in window screens, and has for its object to provide a device of this character so constructed that it can be rolled when not in use and readily unrolledfor having a roller which is controlled by a spring mounted adjacent the roller so that" should the spring break or get out of order 7 it can be replaced or repaired.

Still another object of the invention is to provide a window screen which can be read ily attached to the window frame, and when not in use can be rolled and retained within a casing at the top of the window frame and out of the way.

:With these and other objects in view this ,invention resides in the novel features vof construction, formation, combination and arrangement of parts to .be hereinafter more fully described, claimed and illustrated in the accompanying drawing in-which:-

Figure 1 is a front view of a'window casing showing the device in place.

Secured on the plate 1 adjacent the sid edge of the screen 16 are arms 20 :1 arms having their lower ends provided withbearings 21 for. rotatably supporting the roller 22, said roller being held against accidental disengagement from the bearings 21 by angle; brackets'23, which are secured to the'lower edge of the plate 1 and'adjacent the ends of said roller.

'The'plate' lfisprovided with a recess-24 ,in' which is-Iengaged the screen 16, said screen being engaged with the roller 22 which permits the free movement of the screen and will thus hold the strip 18 alined with the plate 'I-Iooks 25 are pivotally connected to the 27.

at which time the spring 15 will be under:

tension since when the screen is lowered the rollerwill be rotated and rotary movement transmitted to the shaft 12 through the medium of the pinions 10 and 11. Thus it will be'seen that upon releasing the hooks 25 or plates 28 that the screen 16 will rewind upon the roller'f. e
